If you've been in an airport, coffee shop, library or hotel recently, chances are you've been right in the middle of a wireless network. Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at their organization or home, and an increasing number of cities use the technology to provide free or low-cost Internet access to residents. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires. Some care must be taken when setting up a wireless network. Wireless radio signals can be blocked by buildings or trees. They work best when you have line-of-sight between the locations.

The new nursery rhymes:
 
HumptyY  Dumpty sat on a wall,
Humpty Dumpty had a great fall.
All the kings' horses,
And all the kings' men.
Had scrambled eggs for breakfast again, and again, and again.
